摘要: 目的: 探讨辣木叶黄精多糖组合物的抗疲劳作用,并探讨相关的机制。方法: 将30只雄性昆明小鼠随机分为正常对照组(C)、组合物组(MP),每组15只。C组灌胃蒸馏水,MP组灌胃组合物,每组灌胃体积均为0.5 ml。每日灌胃,处理14 d后进行负重游泳实验,按小鼠体质量的3%进行尾部负重,记录力竭游泳时间。在另一项实验中,将48只雄性昆明小鼠随机分为安静对照组(QC)、游泳对照组(SC)、组合物组(MP),每组16只。QC和SC组灌胃蒸馏水,MP组灌胃组合物,灌胃体积均为0.5 ml,每日灌胃,处理14 d。实验第15日,灌胃30 min后,QC组立即取血、肝脏和后腿骨骼肌;SC和MP组进行90 min非负重游泳实验,游泳结束后取血液、肝脏、后腿骨骼肌。采用试剂盒测定血清、组织中的疲劳相关指标、氧化/抗氧化指标、能量代谢指标。结果: MP组小鼠力竭游泳时间较C组显著延长(P<0.05)。与对照组比较,非负重游泳显著降低小鼠血糖和血清谷胱甘肽(GSH)水平、肝糖原和肝脏ATP含量,抑制肝脏超氧化物歧化酶(SOD)、乳酸脱氢酶(LDH)和ATP酶活性,以及肌肉谷胱甘肽过氧化物酶(GSH-Px)活性(P<0.05)。而血尿素氮(BUN)和血清丙二醛(MDA)水平显著升高(P<0.05)。与SC组比较,MP显著增加小鼠血糖和肝糖原含量,增加血清GSH水平、肝脏SOD活性、肌肉GSH-Px活性,增强肝脏LDH、ATP酶活性,增加肝脏ATP含量(P<0.05),降低血清BUN(P<0.05)。结论: 辣木叶黄精多糖组合物具有抗疲劳作用,抗氧化和改善能量代谢可能是其发挥作用的重要机制。

Abstract: Objective: To investigate the anti-fatigue effects of composition of Moringa oleifera leaves and Polygonatum polysaccharide, and to explore the mechanisms. Methods: Thirty male Kunming mice were randomly divided into control (C) and composition of Moringa oleifera leaves and Polygonatum polysaccharide group (MP). There were 15 mice in each group. Group C was given distilled water and the group MP was given composition intragastriclly every day. The volume was 0.5 ml. After 14 days of treatment, weight-bearing swimming experiment was conducted, and exhaustive swimming time was recorded. The bearing weight was 3% of the body weight. In another experiment, 48 male Kunming mice were randomly divided into quiet control group (QC), swimming control group (SC) and composition group (MP). There were 16 mice in each group. The QC and SC groups were given distilled water intragastrically, and the group MP was treated with composition every day for 14 days. The volume was 0.5 ml. On the day 15, 30 minutes after intragastriclly administration of distilled water, blood, liver and hind leg muscle of the QC group were collected immediately. The SC and MP groups were subjected non-weight-bearing swimming experiment, and blood, liver and hind leg muscle were collected after swimming. The fatigue related indexes, oxidant/antioxidant parameters and energy metabolism indicators in serum and tissues were determined by commercial kits. Results: The exhaustive swimming time of mice in MP group was significantly longer than that in the C group (P<0.05). Compared with the control group, non-weight-bearing swimming decreased the contents of serum glucose and GSH, the contents of hepatic glycogen and ATP, the hepatic activities of SOD, LDH and ATPase, and muscle activity of GSH-Px (P< 0.05). However, serum levels of BUN and MDA were increased (P<0.05). Compared with the SC group, the composition remarkably increased the contents of serum glucose and hepatic glycogen, increased serum content of GSH, enhanced hepatic activities of SOD, LDH and ATPase and muscle activity of GSH-Px, and increased the hepatic content of ATP (P<0.05). However, the serum level of BUN was decreased (P<0.05). Conclusion: The Moringa oleifera leaves and Polygonatum polysaccharide composition possesses anti-fatigue effects. Anti-oxidant and improving energy metabolism could be the important mechanisms.

Key words: Moringa oleifera leaves, Polygonatum polysaccharide, anti-fatigue, antioxidant, mice
